You've already got adequate answers, but this is just another way to do it especially fitted for this particular curve, as we'll find out The problem, reformulated, is to find the smallest circle intersecting the curve so that no point on the curve lies within the circle;(*) Dividing by $\,y\,$ assumes $\,y \ne 0\,$, which corresponds to $\,x=0\,$, so this particular solution is included in both sets of solutions found above Share CiteSolve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and more

When we have a sum (difference) of two or three numbers to power of 2 or 3 and we need to remove the brackets we use polynomial identities (short multiplication formulas) (x y) 2 = x 2 2xy y 2 (x y) 2 = x 2 2xy y 2 Example 1 If x = 10, y = 5a (10 5a) 2 = 10 2 2·10·5a (5a) 2 = 100 100a 25a 2 · the angle of rotation to eliminate the xy termx^24xyy^21=0 Solution, Let point (X, Y) be position of point (x, y) after it is rotated θ degreesSimple and best practice solution for X^24xyy^2=0 equation Check how easy it is, and learn it for the future Our solution is simple, and easy to understand, so don`t hesitate to use it as a solution of your homework

 · I think that y = is not meant to be there So I'm going to answer the question "Find the equation of the tangent line to the curve x² 4xy y² = 13Share with your friendsRemark Through unhappy experiences, I have somewhat of an aversion to fractions, so would prefer to say that the equation $x^2xyy^2=0$ is equivalent to $4x^24xy4y^2=0$ But $$4x^24xy4y^2=(2xy)^23y^2$$ Or else, if we feel bad about breaking symmetry, we can avoid completing the square, and instead note that $$2x^22xy2y^2=(xy)^2x^2y^2$$ Again, we have a sum of squares on the right, and this can be $0$ only if $x$, $y$ (and therefore $xy
